Furthermore, the lowest pollen size (length: 18.92 \mum; width: 15.26 \mum), pollen production per anther (19982) and anther length (7.39 mm), but the highest pollen germination rate (40.48 %) and pollen viability (94.93 %) were observed in diploid perennial rye.

Studies On Mushroom Production In Aquaculture With Tuff And Perlite, Şeref Aksu, Ati̇la Günay

Turkish Journal of Agriculture and Forestry

In this study perlite, volcanic tuff and peat moss media were investigated for their possible use in mushroom production in aquaculture between 1994-1995. In mushroom feeding studies, 2% sucrose medium was found to be the most suitable solution for mushroom mycelium growth. Among the 6 different media each containing 2% sucrose, the effect of different rates of micro and macro elements were studied and mycelium growth was investigated. The best liquid medium in relation to the highest dry weight of mycelium was the medium labelled No. 1 which consisted of 10^-3 mol/l of macro and 10^-6 mol/l of micro nutrient …

Assessment Of The Effects Of Rooted Offshoot Properties And Ga_3 Applications On The Yield Of The Globe Artichoke, Günnur Koçer, Beni̇an Eser

Turkish Journal of Agriculture and Forestry

In this study, the effects of rooted offshoot properties and number of GA_3 applications, 30 ppm in concentration, on the early and total yield of the globe artichoke cv "Sakız", produced in one year, were tested. It was determined that when the offshoots, which were at the vegetative growth stage, were used in plantation, higher early and total yields were obtained than that of the generative growth stage. This positive result gained with offshoots at the vegetative stage was also improved significantly with all GA_3 applications, 30 ppm in concentration when compared with untreated plants. Double GA_3 application gave better …

Salinity And Hydrology Of The Fence Road Catchment : A Focus Catchment Of The Blackwood Basin, Ben Whitfield

Resource management technical reports

It is the clearing of native vegetation and replacement with lower water-use annual crops and pastures that is responsible for the developing salinity problem. Traditional farming practices have led to increased recharge to the groundwater systems resulting in increased storage and/or greater areas or rates of discharge. Groundwater monitoring has revealed variable rates of rise throughout the Fence Road catchment, from static to 0.6 metres per year, in a period of average to below average rainfall.

Validation Of The Small Scale Agricultural Production Model In The Community Of Tunshi-San Nicolas, Monica Alexandra Zuniga Donoso

Theses and Dissertations

The model developed in the experimental environment inside the ESPOCH presented satisfactory results. Because of this, it is necessary that the model of production be validated in the farming communities with the purpose of making adjustments before recommending its massive production. In other words, a comparative study should be done on what happened in the experimental farm and what would happen in the community. This is reason why this investigation is titled Validation of the Small-Scale Agricultural Production Model in the Community of Tunshi-San Nicolás. The objectives of the investigation were as follows: Validate the small-scale agricultural production model of …

Obtaining And Sampling Of High Quality Energetic-Protein Mixtures (Pottages) Of Tuber-Cereal-Leguminous Bases In The Candelaria Area, Maria Lilian Maldonado Chavez

Theses and Dissertations

Specially designed foodstuffs destined for children of weaning age in the community of Candelaria were developed and evaluated biologically. These victuals had as bases combinations of tubers-cereals-legumes of high nutritional quality to be implemented in the home. Based on the availability of food and alimentary habits of the region, seven mixtures were formulated of triples and quadruples containing tubers (potato, oca, papaliza, and isano); cereals (rice, wheat, corn, and quinua); and legumes (tarwi, broad bean, and peanut). The cereal-leguminous proportion was maintained as one complement and the addition of the tubers. These mixes were subjected to biological tests, obtaining incremental …

Educational And Occupational Aspirations Of Rural High School Seniors In The Private And Public Schools In Northwest Iowa, Duane Bajema

Faculty Work Comprehensive List

Research has suggested that rural youth have lower educational and occupational aspirations than their nonrural counterparts, and they may experience barriers to educational and occupational attainment. Discrepancies and barriers that may exist have implications for educational policy and educational planning.

Seventeen rural high schools in northwest Iowa were examined; thirteen public and four private schools. Rural high school students were studied to examine their perceptions concerning potential educational and occupational barriers. Student characteristics and qualities were examined based on where the student lived and the type of school they attended. Students who had been involved in the agricultural curricula in …

Department of Agronomy and Horticulture: Faculty Publications

A new method of determining in vitro dry matter digestibility (IVDMD) as recently developed in which the digestion is conducted with the forage samples in filter bags. Our objective was to compare the filter bag and conventional IVDMD analysis methods using smooth bromegrass (Bromus inermis Leyss.), switchgrass (Panicum virgatum L.), and forage sorghum [Sorghum bicolor (L.) Moench] samples. In addition, the filter bag analysis systems for determining non-sequential neutral and acid detergent fiber (NDF and ADF), respectively, were compared with the non-sequential conventional analysis systems. In the filter bag systems, the forage samples are sealed in filter bags and the …

Measurement Of Sorghum Stalk Strength Using The Missouri-Modified Electronic Rind Penetrometer, Jeffrey F. Pedersen, J. J. Toy

Department of Agronomy and Horticulture: Faculty Publications

Resistance to lodging is critical in sorghum [Sorghum bicolor (L.) Moench] grown for grain, yet adequate tools for plant breeders to assess this character at or before anthesis have not been developed. The objective of this study was to evaluate whether an electronic penetrometer previously shown to be an effective tool for measuring stalk strength in maize (Zea mays L.) could be usedd to differentiate among grain sorghum hybrids. Entries in three commercial grain sorghum hybrid trials were evaluated for rind penetrometer resistance (RPR) of the peduncle, the lower stalk anthesis and the lower stalk at maturity. Actual …
